Answer:
D
Step-by-step explanation:
80/100 x 40 = 32
60/100 x 30 = 18
18 + 32 = 50
50/(80+60) x 100 = 35.7
= 36
Thank you
There are 24 sticks in pattern 6. The diagram indicates that one pattern is made up of one box built from four sticks.
<h3>What is the geometric pattern?</h3>
A geometric pattern is a pattern made out of geometric forms that are generally repeated, much like a wallpaper design.
The given figure shows that one pattern consists of one box formed from the 4 sticks.
Pattrern 1 = 1 box
Pattern 2 = 2 box
Pattern 6 = 6 box
1 box = 4 stick
Pattern 6 = 6 box = 6 ×4 = 24 sticks
Hence,there are 24 sticks in pattern 6.

Answer: a.) About 54% of the variation in distance that the driver can see is explained by a linear relationship with the driver's age.
b.) The correlation coefficient, r, is -0.736.
Step-by-step explanation:
The coefficient of determination is denoted
which gives the percent of the variance in the dependent variable that is predictable from the independent variable.
Given, 
That means 54% of the variation in distance that the driver can see is explained by a linear relationship with the driver's age.
Also,
, where r determines the correlation coefficient.
As driver;s age increases the distance he can see decreases, so there is a negative correlation between them.
So r= -736.
Hence, The correlation coefficient, r, is -0.736.
So, the correct options are a.) and b.)
For the 1st one, shade the entire 1st row of squares.
For the 2nd, shade the bottom right square.
